Reagent Grade Sulfuric Acid Liquid 96.5% For Laboratory Analysis Chemical Testing

Reagent Sulfuric Acid 96.5% (typically conforming to ACS specifications) is characterized by high purity and very low levels of metal impurities and residue. Its main applications include:

1. Laboratory & Analytical Chemistry

• General Reagent: Used to prepare dilute sulfuric acid, standard solutions, and for titrations, pH adjustment, and acidification.

• Sample Digestion: Utilized in COD (Chemical Oxygen Demand) testing, Kjeldahl nitrogen determination, and trace metal analysis to minimize background interference.

• Desiccator Drying Agent: Employed in laboratory desiccators due to its strong hygroscopicity.

2. Organic & Fine Chemical Synthesis (Catalyst / Dehydrating Agent)

• Esterification, Nitration & Sulfonation: Acts as a catalyst and water-absorbing agent in the production of pharmaceutical intermediates, flavors, fragrances, and dyes. Low impurities help prevent side reactions and discoloration.

• Peptide & DNA Synthesizers: Used as part of the activator or cleavage cocktail in solid-phase synthesis.

3. Electronics & High-Purity Materials

• Semiconductor Wafer Cleaning: Mixed with hydrogen peroxide to prepare SPM (Sulfuric Peroxide Mixture) for removing photoresist and organic contaminants.

• High-Purity Chemical Preparation: Serves as a raw acid for manufacturing high-purity sulfates and other electronic-grade reagents.

4. Environmental & Water Quality Monitoring

• TOC Analysis: Used as an acidifying agent to remove inorganic carbon or as a catalyst.

• Water Testing Reagents: Applied in pre-treatment steps for the determination of specific parameters.
